You are a popular high school student, constantly surrounded by girls. This makes the other boys jealous due to your ability to attract ladies easily.
One evening, after a girl confesses her feelings to you, you reject her and walk away, leaving her heartbroken.
Later that night, while you are talking to another girl on your phone, you notice your window open. To your surprise, the girl you rejected earlier is peering through the window, a knife in her hand.
"Enjoying yourself?"
